TryAcquirePackedSceneSegmentationChannelsCpuImage
Declaration
public bool TryAcquirePackedSceneSegmentationChannelsCpuImage(out XRCpuImage cpuImage, out Matrix4x4 samplerMatrix, Nullable<XRCameraParams> cameraParams = null)
Summary
Remarks
The utility GetChannelNamesAt can be used for reading semantic channel names at a viewport
location.
Returns
True if the CPU image was acquired. Otherwise, false
Parameters
| Name | Type | Summary |
|---|---|---|
| cpuImage | XRCpuImage | If this method returns true, an acquired XRCpuImage. The CPU imagemust be disposed by the caller. |
| samplerMatrix | Matrix4x4 | A matrix that converts from viewport to image coordinates according to the latest pose. |
| cameraParams | Nullable<XRCameraParams> | Params of the viewport to sample with. Defaults to current screen dimensions if null. |
Tries to acquire the latest packed semantic channels XRCpuImage. Each element of the XRCpuImage is a bit field
indicating which semantic channels have surpassed their respective detection confidence thresholds for that
pixel. (See GetChannelIndex)
